On all 2000+ boxsters the pre-cats or warm up cats right by the motor are eliminated with all aftermarket headers except Fabspeeds which are a header with high flow cats.

Che, you need to bring a Fabspeed header knockoff to market and sell it for half the price. You'd probably sell a ton if you can make something like these. As you probably know, all the bungs in the world won't prevent a CEL from happening unless you have some cats.

He doesn't mention if the 4 bung headers will cause a CEL or not. My guess is they will. I guess we'll see once somebody tries them.

fu03steve · 05-12-2008, 08:02 PM

so those 4 bung are for the o2 sensors then huh?

if i was to remove the 2ndary cat close to the muffler...
will CEL turn on/?

Yeah, it probably will. In layman terms the sensors that were aft of the cats will sense too much pollution and think your cats are not functioning properly so there's a good chance it will trip a CEL light.

Che has totally disappeared from this site. I guess business is good.

That's too bad because like many others on this site I am interested in his headers but not without having the questions posted on this thread answered first regarding the CEL's

so a better solution is probably to keep the cat by the muffler...
and remove the first cat along with the headers?

would that be better?

Hey Che, Any plans on offering secondary catalyst bypass pipes for the later cars that have two converters on each side? Im sure you could make a nice product and still undercut the other options by alot! Thanks
